New records of Geastraceae (Basidiomycota, Phallomycetidae) from Atlantic Rainforest remnants and relicts of Northeastern Brazil. This work presents records of Geastraceae for northeastern Brazil, collected in remnants of the Atlantic Rainforest and Atlantic Rainforest relicts "Brejo de Altitude". The species were identified based on macro- and micromorphology with the aid of specific literature. Eleven species of the family are distributed into two genera: Geastrum fimbriatum, G. javanicum, G. lageniforme, G. lloydianum, G. minimum, G. pectinatum, G. rusticum, G. schweinitzii, G. setiferum, G. triplex, and Myriostoma coliforme. Nine of these records are new for Rio Grande do Norte state, five for Paraíba and five for Ceará. Geastrum minimum is the first record for Northeastern Brazil; G. rusticum is the first report for the semiarid region, while G. pectinatum and M. coliforme are the first records for the Northeastern Atlantic rainforest and "Brejo de Altitude" vegetation. We also provide observations, habitat, and species distribution in Brazil.
